摘要：

为了探讨地表粗糙长度和地形起伏度空间分异对武夷山自然遗产地植被景观格局性质的影响，利用ArcGIS 9.0和景观指数软件分析各地表粗糙长度和起伏度带上的景观指数。结果表明：景观的面积、斑块数量、景观多样性指标、优势度指标随着地表粗糙长度指数的增加，而呈现“增加—减少—增加”的趋势，在粗糙长度为7的级别上达到最大值；破碎度指数、景观面积周长比分维数值随粗糙长度的增加，呈现先减少后增加的“U”型曲线；景观面积指标、景观斑块数量、景观破碎度、景观多样性指标、景观优势度随着起伏度的增加而呈递减趋势，只有景观斑块的面积周长比的分维数在800 m

Abstract:

In order to study law of landscape pattern indices responding to surface roughness length and surface relief mountain factors spatial heterogeneity in the Wuyishan natural heritage vegetation landscape. With ArcGIS 9.0 and landscape index software, landscape indices at different surface roughness length and surface relief mountain landscape were studied. The results showed that curves of landscape area index, patch number index, landscape diversity index, landscape dominance index increased and then decreased, furthermore increased with increasing surface roughness length, the highest value accrue at 7 degree, landscape fragmentation index, fractal index of area and perimeter ratio showed ‘U’ type curves with surface roughness length increasing; landscape area index, patch number index, landscape diversity index, landscape dominance index increased and then decreased with the increasing surface relief. Only fractal index of area and perimeter ratio showed the lowest value at 800 m
